Just wondering if anyone else is having this issue or not. I have the plastic fender flares with the sasquatch package so I expected mud and rocks to sling up but i can't seem to get them cleaned. I haven't taken it "off-roading" really. All the mud I've picked up from my short dirt driveway and anything on the highway. Washed it first with a soft wash mitt, soap and water and it dried like the photos. I tried a harder sponge and scrubbed it pretty hard and today I took it to a car wash and used the pressure washer and still no change. The dark spot on the fender is just a wet spot I tried to clean with my thumb. It dried like everything else. Thanks in advance.
